Outcomes following surgical intervention for acute hemorrhage in severe traumatic brain injury: a review of the National Trauma Data Bank.

OBJECTIVE

Severe traumatic brain injury (TBI) is a public health issue posing significant morbidity and mortality to afflicted patients. While the effect of time to surgery as the primary factor for survival has been extensively studied, long-term dispositional outcomes following intracranial hemorrhage evacuation have not been well described in the literature. Therefore, the aim of this study was to elicit potential prognostic factors in patients presenting with severe TBI that may have a significant impact on discharge disposition.

METHODS

The authors searched the National Trauma Data Bank (NTDB) for patients included between 2010 and 2019, solely focusing on those with a Glasgow Coma Scale score ≤ 8, signifying severe TBI, and with associated intracranial hemorrhage treated via surgical intervention. Numerous characteristics were analyzed, including demographics (age, sex, race, ethnicity, payment status), discharge disposition, time to surgery, pupillary response, midline shift (> 5 mm), and postoperative inpatient complications and comorbidities. Disposition included routine discharge to home, discharge to home with home health services (HHSs), discharge to acute inpatient rehabilitation (AIR), discharge to a skilled nursing facility (SNF)/long-term acute care hospital (LTACH), and death.

RESULTS

The authors analyzed data on 7308 patients, 69.6% of whom were White and 11.2% of whom were Black. More young Black and Hispanic patients had severe TBI events than their matched elders, whereas more elderly White patients had severe TBI events than their matched younger counterparts. The most common disposition across all ages was SNF/LTACH. Septuagenarians and octogenarians were 12.1 and 21 times more likely, respectively, to die following a severe TBI than their younger counterparts (p < 0.001). Patients aged 18-29 were 1.7 times more likely to be discharged with HHSs (p < 0.001). Minority race/ethnicity groups were less likely to be discharged to AIR. As age increased, a patient's intensive care unit stay increased by 15 days (p < 0.001) and total hospital length of stay increased by 25 days (p < 0.001).

CONCLUSIONS

Neurosurgical evacuation of intracranial hemorrhage in severe TBI has variable long-term morbidity. Utilizing the largest collection of trauma data within the United States, the authors present quantitative evidence on discharge disposition. Understanding these tangible points can help neurosurgeons present potential outcomes to patients, promote preventative care, and generate tangible conversations with patients and their family members.
